Provides the force manager for Isothermal-Isobaric Langevin Dynamics where the stochastic force |
| 44 |
|
|
is applied to the surface atoms anisotropically so as to provide a constant pressure. The |
| 45 |
|
|
surface atoms are determined by computing the convex hull and then triangulating that hull. The force |
| 46 |
|
|
applied to the facets of the triangulation and mapped back onto the surface atoms. |
